Police were required at the Olympiahalle in Munich tonight after British heavyweights David Haye and Dereck Chisora brawled with each other in an incident which saw Haye's manager Adam Booth suffer a nasty facial cut.

After losing a brave 12-round decision to WBC champion Vitali Klitschko, Chisora mocked the onlooking Haye for his poor performance against Klitschko's brother Wladimir last year and tried to goad his rival into a future bout.

Chisora then confronted Haye during the press conference and the two men grappled around the room with onlookers and entourages getting involved. At one stage Haye swung a camera tripod violently at Chisora's trainer Don Charles after trading blows with him, while Chisora brandished a glass bottle moments later.

Booth somehow suffered a gash on his forehead and claimed to have been 'glassed'.

Police arrived as the incident calmed down and were on hand as Chisora eventually left the arena some time later. Detectives refused to confirm whether official action has been taken or whether an investigation is planned.
